A new strategy to simultaneous removal and recovery of nitrogen from wastewater without NO emission by heterotrophic nitrogen-assimilating bacterium.

Biological assimilation that recovery the nitrogen from wastewater in the form of biomass offers a more environmentally friendly solution for the limitations of the conventional wastewater treatments. This study reported the simultaneous removal and recovery of nitrogen from wastewater without NO emission by a heterotrophic nitrogen-assimilating Acinetobacter sp. DN1 strain.

Integrative chemical and omics analysis of the ammonia nitrogen removal characteristics and mechanism of a novel oligotrophic heterotrophic nitrification-aerobic denitrification bacterium.

A novel oligotrophic heterotrophic nitrification-aerobic denitrification bacterium designated as Pseudomonas sp. N31942, was isolated from a eutrophic lake. Strain N31942 exhibits high ammonia nitrogen removal ability in oligotrophic environment as ammonia nitrogen can be efficiently (86.

[Selective enrichment of phosphopeptides with aspartic acid based immobilized metal ion affinity chromatography materials].

A natural amino acid, aspartic acid, was modified to bind to silica microspheres with a click chemistry method (-Click Asp).The modified Click Asp microspheres were further modified by incorporating Fe ions, resulting in Fe and Click Asp based immobilized ion affinity chromatography (IMAC)(Fe-Click Asp).The prepared materials were characterized using Fourier transform infrared spectrometry, X-ray photoelectron spectrometry, and scanning electron microscopy, and it was confirmed that Fe-Click Asp was successfully prepared.
